<h1>Descripci&oacute;n General</h1>
<p>Una fuente de datos Meta toma su nombre porque permite combinar puntos existentes en nuevos puntos. En lugar de tomar la informaci&oacute;n de una fuente de datos externa, utiliza los valores de puntos internos, y los manipula a gusto.</p>

<h1>JavaScript / ECMAScript</h1>
<p>Este tipo de fuente de datos requiere conocimiento de JavaScript, y de ECMAScript. (Las especificaciones completas de ECMAScript se encuentran en <a href="http://www.ecma-international.org/publications/standards/Ecma-262.htm" target="_blank">aqu&iacute;</a>.) 
Para muchos, JavaScript es el lenguaje m&aacute;s popular para la programaci&oacute;n de scripts de hoy en d&iacute;a, es el &uacute;nico lenguaje disponible
para todos los navegadores populares. Como resultado esta popularidad es el uso com&uacute;n del JavaScript en las p&aacute;ginas webs. El contexto 
dentro de las fuente de datos Meta es diferente, no hay objetos "ventana" o "documentos", adem&aacute;s de otras diferencias. 
Junto a las diferencias contextuales, una implementaci&oacute;n completa de ECMAScript est&aacute; disponible en las fuentes de datos. Espec&iacute;ficamente la implementaci&oacute;n <a href="http://www.mozilla.org/rhino/" target="_blank">Rhino</a> es utilizada.</p>
